SPRiNG BED-BOTTOM.

SPEGIFICATISN forming part of Letters Patent No. 353,360, dated November 30, 1886.

To aZZ whom it may concern:

Be it known that 1, ROBERT W. HOM'AN, a citizen of the United States, and a resident of Brooklyn, Kings county, in the State of New York, have invented a new and useful Iinprovement in Spring Bed-Bottoms, of which the followingis aspecification, reference being had to theaccompan yingdrawin gs, which form a part thereof,

IO My invention relates to that class .of bedbottoms provided with slats and coiled springs, and is intended as an improvement upon an invention upon which an application is now pending, filed by the February 2, 1885, Serial I No. 156,716. r

The object of my invention'is to construct a slatted spring bed or mattress that shall cur body therein certain folding qualities at its center, and yet be rigid to a certain extent, as

well as to contain certain independent adj ustments, consisting of double or cross jointed links in combination with the former, that will not only enable the manufacturer to more conveniently pack for shipping, but also enables the user to adjust the same to the varied width of frames without changing the position of the central parts. By the construction and combination of partsliereinafter described the manufacturer is enabled to produce a slatted spring-mattress that is not only adjustable by means of double cross-jointed links for various widths of bedsteads, but adapted to be folded at the center thereof for more convenient handling and packing, the central slats maintainlaterally, making the extension of the adjustable links across the center unnecessary, therefore less expensive to construct.

Referring to the drawings, Figure 1 repreresents atop view of my improved bed-bottom open, and showing the cross jointed links in position, and in combination with the side parallel slats, also the spring-folding connections. Fig. 2 is a top view of Fig. 1, with the slats closed and ready for folding for shipment. Fig. 8 is an end view showing the slats and spring folded for shipment, or for storing away when not in use. Fig. 4 is a sectional edge view.

In the drawings, A represents. the slats ar- 50 ranged parallel in their relation to each other;

ing at all times iixed relations to each other- 13, slats elevated above the others, A, at each side of the top,which not only serve to connect the rows of springs thereon, but also to prevent their tilting when such slats are connected with the lower ones by the angle or flexible 5 brace hereinafter specified; O O, springs.

D D are flexible arms or connections, more clearly shown in Fig. 4: of the drawings, composed in this particular instance of a suitable strip of narrow springy metal bent at an angle, one end of which is secured to the top slat, B, and the other to the slat or slats A below.

E E are links of metal jointed together substantially at three points, the object of this double-jointed arrangement of links being to 6 connect the outer slats, A, in such' manner as to prevent undue end motion of the said lower slats; F, guide slide-pins; F, guideways for slide-pins; G, elastic connectingbar for holding the center slats in position when in use. I do not wish to be understood as claiming, broadly, an adjustable spring-bed, neither a spring-bed adapted to be folded at its center. Neither do I claim connecting slats by links, for such parts have been employed before; but

\Vhat I do claim is- 1. The combinatiomwith a series of slats arranged parallel with each other,the center ones being secured in a fixed position by spring cross-slats rigidly secured thereto and adapted for folding, of adjustable outer slats operating in connection with the former in such a mannor as to adapt the said bottom to beds of varied widths, substantially as set forth.

2. The combination, in a bedbottom, with a series of centrally-located slats held in a fixed parallel position to each other by means of spring cross-pieces rigidly attached thereto, of connecting adjustable slats supporting a slat or side rail above, substantially as and for the 0 purpose set forth.

3. A spring bed-bottom consisting ofa series of connecting-slats, the center ones being non-. yielding in respect to width, but adapted to be folded, provided with outside connecting- 5 slats adjustably held and operated by means of cross-linked devices supporting slats or rails above, substantially as and for the purpose set forth.

4.. A spring bed-bottom provided with aseioo' ries of central slats rigidly secured together lateral relation to each other, and supporting 10 in respect to their lateral relation, to which a series of coiled springs above, and adj ustalso are connected outer adjustable slats held able outer side slats, and one or more angular and operated by cross-linked connections sup- I spring-arms supporting upper side slats or 5 porting upper side slats, and a series of coiled rails, substantially as set forth.

springs united by chains, substantially as set ROBERT WV. HOMAN. forth. Witnesses:

5. A bed-bottom consisting of a series of JOHN DANE, J12, central slats rigidly fixed in respect to their J OSEPH M. CRANE.
